FGF-8 CRISPR/Cas9 KO Plasmid (h): sc-403127
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- FGF-8 CRISPR/Cas9 Knockout (KO) Plasmid (h) is a pool of plasmids, each encoding Cas9 nuclease and a target-specific 20 nt guide RNA (gRNA) designed for maximum knockout efficiency using sequences derived from the GeCKO v2 library
- gRNA sequences direct Cas9 to induce site-specific double-strand breaks (DSBs) in the FGF-8 genomic locus, resulting in gene knockout through non-homologous end joining (NHEJ)
- The puromycin resistance and RFP genes are flanked by LoxP sites, enabling removal of selection markers via Cre recombinase (Cre Vector: sc-418923) after establishing stable knockout cell lines
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: FGF-8 Antibody (2A10): sc-293479

Overview
FGF8 encodes fibroblast growth factor 8 (FGF-8), a secreted signaling ligand that binds FGFR family receptors to regulate embryonic patterning, tissue morphogenesis, and cell fate decisions. FGF-8 activates canonical RTK pathways including RAS–MAPK/ERK, PI3K–AKT, and PLCγ signaling, influencing proliferation, migration, and differentiation programs in a context-dependent manner. Dysregulated FGF8 expression and FGFR pathway activity have been linked to developmental abnormalities and to oncogenic signaling networks in multiple tumor types, where altered growth factor signaling can remodel lineage programs and microenvironmental interactions. In research settings, FGF8 is commonly studied for its roles in developmental biology, growth factor–dependent transcriptional programs, and pathway crosstalk controlling tissue homeostasis.
FGF-8 CRISPR/Cas9 KO Plasmid (h) is a pool of plasmids designed for targeted disruption of the FGF8 gene in human cell lines. Each plasmid co-expresses a unique single guide RNA (sgRNA) targeting a distinct site within the FGF8 together with the Streptococcus pyogenes Cas9 nuclease. The plasmids also encode GFP, allowing fluorescent identification and enrichment of successfully transfected cells by fluorescence microscopy or flow cytometry.
The multi-guide design increases the likelihood of generating insertions or deletions (indels) that disrupt the FGF8 open reading frame following Cas9-mediated double-strand break formation. DNA breaks introduced by the CRISPR/Cas9 system are repaired through endogenous non-homologous end joining (NHEJ) pathways, frequently resulting in frameshift mutations that abolish FGF-8 protein expression.
This CRISPR knockout system enables efficient generation of FGF8-deficient cell models for investigation of FGF-8 signaling, functional genomics studies, cancer biology research, and evaluation of therapeutic responses in human cell lines.

Design Variants
CRISPRs +/- HDRs
- gRNAs encoded by FGF-8 CRISPR/Cas9 KO Plasmid (h) and FGF-8 CRISPR/Cas9 KO Plasmid (h2) target distinct sites within the FGF8 locus. One or both targeting designs may be available. See Related Products for availability.
- HDR donor constructs encoded by FGF-8 HDR Plasmid (h) and FGF-8 HDR Plasmid (h2) contain a puromycin resistance cassette and an RFP reporter flanked by FGF8 homology arms to support homology-directed repair at defined FGF8 target sites corresponding to the CRISPR/Cas9 KO designs. HDR donor availability may vary. See Related Products for availability.
